OLP (Optical Line Protection) is a device used in pairs, one at each end of the optical signal to protect the network transmission line. It can realize optical power monitoring and automatic switching. In optical communication networks, OLP monitors the optical power of optical fiber and standby optical fiber in real time. In case the current optical power of the optical fiber is less than pre-set switching threshold value, then alarm is on and it would switch to standby optical fiber automatically to protect the optical transmission system line. OLP system will provide a more reliable, flexible and high secure optical transmission network, which is widely used for protecting backbone and important business line.
The OLP can be used with FMT series products, which provides cost-effective and flexible WDM solutions. It has a variety of optical layer boards and provides excellent optical performance, and can be applied to DWDM dual-fiber/DWDM single-fiber/optical cable monitoring systems, to meet the diverse needs of scenarios.
